SPECIFICATION forming part of Letters Patent No. 628,393, dated July 4, 1899.

Application filed October 13, 1898 To all whom, it may concern:

Be it known that I,THoMAs OLIVER COOPER, a citizen of the United States, residing at Wilmington, in the county of New Castle and useful Improvement in Electric Railway- Gates; and I do hereby declare the following to bea full, clear, and exact descriptionof the same, reference being had to the accompanying drawings, in which- "Figure I is a face view of a switchboard to be located in the gearbox of each gate and a plan of a system of rails and connections on a railroad. Fig. II represents a switchboard with trolleys and connections on an engine to engage the said tracks. Fig. III is aside view of a gate raised and its gear-box, certain portions being broken away. Fig. IV is Fig. V is an edgewise View of the operating-disk. Figs. VI and VII are detail views showing portions of the gate-switchboard in horizontal section. Fig. VIII is a side view of a trolley.

This invention relates to that class of derailway-crossings and its object is to provide mechanism, including electrical communications, whereby an engineer on an engine may control one gate or a series of gates, including those at every crossing in a town on his track, both to close and to open each and all ofthe gates at will while his engine is moving either forward or backward or standing still at any point near the gates.

To this end my invention consists in the construction and arrangement of parts forming an electric railway-gate, hereinaftermore fully described, and particularly set forth in the claims.

With reference to the drawings, numeral 1 represents a gate to be located at a railwayand 3 an operating-disk, all rigidly mounted on a shaft 4, which is journaled to rotate onequarter of a revolution to and fro in the gearbox 5 to close and open the gate both by positive action.

The contact-piece 61 is metallic to connect electrically with switchspring 56 and joined byan insulator 62 with the body of lever 58 as an arm thereof.

63 is a rod of insulating material pivotally connected with switches 47, 50, and 54 and with a lever 64, which is pivoted at 65.

Wires 113 and 114 connect the signal-box 108 withthe spring 99 and' switch 95, whereby a local circuit is completed when the switch is closed. This signaling device may be located at any convenient point to observe the action of a gate or one for each gate in a town. SWitch-sprin gs 115, 116, 117, and 118 are located upon the board 78 and permanently connected, respectively, with wires 124, 120, 121, and 122, and those springs are hung to be pushed into contact with points, respectively, of Wires 123, 155, 125, and 126 by means of a cam 127 upon the disk 3.

128 is a cam on the disk, which presses spring 107 down upon lever 105 as the gate nears the end of its upward course, so that when stud 102 pushes lever 105 back the spring-detent 107 engages and holds it.

133 and 134 represent signal-bells, each provided with means to be electrically operated and located near the gate.

135 and 136 represent electric lamps to be located upon .the gate.

Numbers 137 to 163 represent wire connections for electric communication with parts on the switchboard 78.

The rails described are located along the road-bed far enough at each side of every gate to give due warning and to close the gate before the engine is near enough to render crossing dangerous.

In Fig. VIII, I show one means of hanging the trolleys. Each trolley is mounted to slide vertically in a frame 180, which is loosely hung,,by means of trunnions 164, in slots in hangers 165, that are attached to some convenient portion of the engine or tender, so that the frame of trolleys will hang by the springs 166 and trail in either direction when in service. 167 represents a lever by which the fireman may lift the frame of trolleys whenever required, and over long stretches between crossings it is safer to hold the trolleys raised far above the road by securing the lever 167 with a catch 168.

Thus far the description'is based on the supposition that wire 169 connects with the positive pole of the generator 10 and 170 with the negative pole. Now the pole-changers 11 and 16 being connected by a wire 174 and the changers 12 and 15 by wire 175, if the switches 13 and 17 be turned upon the changers 12 and 16, respectively, the direction of the current will be such that wire 32 will be positive and wire 31 negative. In backing an engine this is not required; but it is required when the engine is turned around to run the other way on the same track.

Operation: Let us suppose an engine provided with an electric generator 10 and the trolleys, switches, and connections described to be moving on the track A in the direction of the arrow a toward gate 1. In order to close the gate, the engineer sets switch 20 upon wire'30 and switch 23 upon wire 26. This introduces a current from generator 10 over wire 21, switch 20, wire 30, trolley 34, rail 41, and wire 149 to magnet 86, from which the circuit returns over wire 126, contact-point of spring 118, which is at this time held in contact by segment 127 through the said spring, and over wires 122 and 124, rail 45, trolley 38, wire 26, switch 23, and wire 24 back to the generator 10, completing a' metallic circuit,

whereby the magnet 86 is energized and attracts the armature 87 to draw the rod 80, with its wedge 81, against spring 83, bringing it into contact with elbow-lever 66. This is completed in an instant of time, so that the switches 20 and 23 may be immediately returned to their open position, as shown. Now the hand-levers 17 13 may be set in contact with the rheostat-buttons, whereby the current is introduced from generator 10, with any desired degree of force, over wire 169, rheostat 11, lever 13, wire 31, trolley 33, rail 40, wire 145, switch 50, spring 53, and wire 171 to the motor 9, whence the currentreturns over wire 154, spring 83, which was set in contact with elbow-lever 66, thence over wires 140 and 142, rail 46, trolley 39, wire 32, switch-lever 17, rheostat 15, and wire 170 to the generator 10. The circuit being thus complete through the motor 9, it rotates the worm 8, by which spur-gear 7, worm 6, and segment 2 are operated to turn the shaft 4 and with it the gate 1 to close the same. The disk, revolving with the segment 2 and shaft 4, brings pin 97 against the'edge of lever 66, pushing the arm 68 to the position shown by dotted lines 172 and raising the other arm of lever 66 and with it the connecting-rods 71 and 63 and setting switches 47 50 in contactwith their respective springs 49 and 52, whereby the direction of the path of the current is reversed. This movement also bears the arm 58 upward and the arm 61 to the right and raises the switchspring 56 into the path of arm 61, as shown in dotted lines, and in raising spring 56 the opposite end of lever 54 is carried under the hook of mechanical spring 57, which at this time is pressed into engagement with the said lever 54 by segment 129 on disk 3, whereby the rods 71 and 63 and the parts directly connected thereto are held stationary. The raising of rod 7l-operates lever 85 against stud 79 and draws rod 77 with wedge 81 from spring 83 and breaks the contact between the latter and elbow-lever 66, thereby interrupting the generator-circuit. In reachingits present position, with the gate down, the disk 3 has carried the stud 102 against the arm of switch 100 and closed the latter with the spring 103. Now to raise the gate the engineer throws switch 17 out of connection and he connects wire 24 with wire 25 by means of switch 22, establishing a circuit which, starting at the generator 10, passes over wire 169, rheostat 11, switch 13, wire 31, trolley 33,track 40, wires 145 and 146- switch 50 53 having been opened by the raising of rod 63through electromagnet 130, over wire 153, through set switch 100 103, over wire 150, rail 43, trolley 36, wire 25, switch 22, and wire 24 back to the generator. The magnet 130 being energized lifts its armature 131 with pin 97, removing the latter from engagement with arm 68, permitting the same to be restored to its normal position, as shown in full lines, by means of elbow-lever 58 and spring 60. The flange 69 now stands in front of the raised stud 97 to prevent the stud from passing in front of arm 68 under any circumstances, as something would be broken if the gate were to be raised with the pin at the wrong side of that arm. The action of spring on lever 58 also restores the latter to its normal position, as shown in full lines, at the same time making contact with spring 56, which is in the position of the dotted lines, whereby the reverse circuit is completed for operating the motor 9 to raise the gate. To do this, the engineer throws off switch 22, breaking its connection with wire 25, and turns on switch 17, whereby the current is turned into circuit, which, starting at the generator 10, passes over wire 169, rheostat ll, switch 13, wire 31, trolley 33, rail 40, wire 145, switch 50 52, and wire 144 to the motor at that pole which was formerly the negative, but now made positive to reverse the action, thence returning over wire 143, switch 54 56 61, wires 141, 140, and 142, rail 46, trolley 39, wire 32, switch 17 rheostat 15, and wire 170 to generator 10. The motor being operated raises the gate by means of the connecting-gearing. The first action of the returning disk 3 is to carry pin 102 away from arm 100, permitting switch 100 to be retracted by spring 104, breaking contact with spring 103. The second action is to carry pin 97 back off from arm 68, when the armaturespring returns that pin to its normal path behind arm 68 and ready to engage it again. The final result is the restoring to their normal positions, as shown in full lines, of rods 71 and 63 and their positive connections, the switches 50 52, 47 49, and 56 61, which are all opened, and the switch 50 53, which is closed, all by the pin 102 acting through lever 105, spring-arm 106, and lever 64 upon the said rod 63. At this time segment 128 on disk 3 presses spring-detent 107 into engagement with arm 105, holding the connected switches from being disarranged.

- Streets to be crossed in cities are frequently so close together that a second gate, or even a third gate, should be closed before a fastapproaching engine reaches the first gate, so it becomes necessary to form electric connections which pass one or more gates, and yet it is not practicable to continue all the electrical rails through a city, because that would close allthe gates by the act of closing one, so that travel on all the streets would be interrupted even though the engine needed to cross only the first street. For this and other reasons I break, as at 173, part of the rails at each crossing and continue other rails past the crossings, and the center rail I break midway between crossings.

In my system of construction seven electrical rails are located along between the tracks far enough at each side of every gate to give due warning and to close the gate before an engine can reach there. Three of these rails 40 41 42 are continuous where there are many crossings and serve as conductors from the generator on the engine to the 1110-.

tors which operate gates, one at each crossing. The three corresponding rails 46 44 complete the circuits back to the generator and are the ones broken at crossings.

In order to complete the circuit for operating the gate by an engine backing from the left toward the gate, the switch 74 76 is provided to operate as follows First, the switches 20 and 23 are to be set to engage, respectively, the wires 29 and 27, which completes a circuit from generator 10 over wire 21, switch 20, wire 29, trolley 35, rail 42, wire 152 to magnet 88, thence returning over wire 125 and spring 117, which are now in contact, over wires 121 and 120, rail 44, trolley 37, wire 27, switch 23, and wire 24 to the generator. The magnet 88 being energized, attracts armature 89 and mechanically draws the elbow-lever 66, by means of rod 90, farther to the right than it has been heretofore moved, and in so doing draws down rod 72 and sets the switch 74 into engagement with spring 76. The rod 71 is slotted to permit the stud on lever 66 to play down freely, so that said rod 71 will not be moved by setting the switch 74 76. This switch being set completes a circuit which, starting at the generator 10, passes over wire 169, rheostat 11, switch 13, wire 31, trolley 33, rail 40, wire 145, switch 53, and wire 171 to the motor 9, and returns over wires 154 and 137, switch 74 76, wires 138 139, rail 46, trolley 39, wire 32, switch 17, rheostat 15, and wire 170 to generator, which energizes the motor 9 to close the gate, as before described. The pin 97 operates elbow-lever 66, and thereby raises rod 72 and opens the switch 74 76 at the same time that certain parts are reset, as before stated. The rod 72 is slotted for the stud on elbow-lever 66 to permit the usual operation at first described without then operating the switch 74 76. The gate is to be opened by exactly the same manipulation as at first described for that purpose, because rail 46 is now connected over wire 139 and the closed switch 47 49 with wire 140, completing the circuit as rail 46 formerly did over wire 142. The rail 45, being connected by wire 123 with the contact-point of spring 115, is in circuit with rail 45 over wire 124 whenever the gate is down, for then the segment 127 holds the spring 115 in contact with that point, thus forming a bridge over the gap 173. A similar result is effected with rails 44 and 44 through their connections 120 and 155 with spring and contact-point 116, that contact being also made by pressure of the same segment 127 at the same time. The gap 173 is made because otherwise all circuits for one gate would be complete through all the gates on one system; but the next gate is so near as to require notice of an approaching engine before the engine reaches this gate. Therefore when this gate is closing it is made to close the circuits at 115 and 116, whereby the gap is bridged directly, so that the current passes on and the closing of the next gate takes place. This operation will be repeated as far as the bridging is carried out, each succeeding gate starting to close when its predecessor is near the closing-point; but if the engineer chooses not to close the second gate he throws off the switches that would otherwise continue the operation.

If for any reason the engineer wishes to stop the closing of the gate after it has begun, he may reverse all the connections which effeet that action and cause the gate to reopen from that point by first disconnecting switches 20 and 23 from whichever wires they were in circuit with also, he disconnects switch 17 and sets switch 22 in connection with wire 28, which completes the circuit from generator 10 over wire 169, rheostat 11, switch 13, wire 31, trolley 33, rail 40, wires 145, 146, and 147 to electromagnet 91, and return over wires 14S and 149, rail 41, trolley 34, wire 30, switch 22, and wire 24 back to the generator. The magnet 91 being thus energized attracts armature 92, which pulls on the upper arm of elbow lever 66 by means of spring 94 and rod 93. This raises rods 71 and 63 and lever 58, breaks the acting circuit by opening switch 50 53, and stops the gate, closes switches 47 49 and 50 52, and sets switch 61 56 ready for engagement. Now the stopped gate may be raised and reopened in full by first turning switch 22 off from wire 28, which cuts out the magnet 91 and releases armature 92 and permits elbow-levers 58and 66 to be returned by spring 60 and the switch 61 56 to be engaged. The turning off of switch 50 53 and turning on of switches 50 52 and 47 49 reversed the direction of the current to the motor. Now by turning on switch 17 the circuit is completed to the generator, as before described, and the motor is actuated to raise the gate. It will be understoodby this that the means of controlling the action of the motive parts is so complete that the gate may be closed or opened or theaction of either operation may be suspended and reversed at any point at the will of the engineer.

Should anything occur to prevent the engineer from opening one or more gates when passing, he can open all such in one series at one operation, as follows: Let us suppose that the gates have all been put down and all hand switches of the system open. The first movement for the engineer is to connect switch 13 with rheostat 11; second, to set switch 22 on wire 29, thereby completing a circuit from generator to motors of all the gates thus: from generator 10 over wire 169, rheostat 11, switch 13, wire 31, trolley 33, continuous rail 40, and wires 145 146 to magnet 130, and returning over wire 153, switch 100 103, wires 151 152, continuous rail 42, trolley 35, wire 29, switch 22, and wire 24 to generator. This energizes magnet 130 and draws pin 97, from which time the action is in all respects the same as that first described for opening one gate, with the exception that in this instance both the outgoing and return currents are over continuous rails, so that any impulse given to one switch would be given to all in like condition in that system. The bell 133, connected with the circuit of magnet 86, will be sounded when that magnet is energized to perform its part in closing a gate, and bell 134 is connected with circuit of magnet 88, to be sounded when that magnet is energized, forsounding alarms at the crossing by engines coming from either way. 95 is a lever one arm of which projects over the disk 3 to the path of stud 98, the other arm being arranged to contact with a spring 99 as a switch for connecting the Wires 113 and 114:, which come from a battery in signal-box 108. 109 is a bell, and 110 is an annunciator connected by a rod 111 with mechanism in box 108. When the gate reaches the point of being closed, the pin 98 on disk 3 comes against lever'95' and closes the switchwit-h spring 99, whereby the circuit of the battery in box 108 is closed, and the bell 109 is thereby sounded one stroke and the annunciator 110 is set to show the sign Closed. This sign will remain until the gate opens, when pin 97, nearing the end of its return path, comes against the lever 95 and opens the switch, when the annunciator will be changed to show the sign Open.

. A bell and annunciator for each gate may be located in the oliice of any person whose duty or desire it is to note the operation of the gates, and its operation is dependent,

only upon the movements of the gate and its own battery entirely independent of control by the engineer, whereby careful watch may be maintained at a point distant from the gates over the gate operation as a check against carelessness of the engineer. 135 136 represent lamps to be located upon the gatearm, one being connected with the electric circuit of one side of the gap and the other with the other side, whereby an engine at either side of the gap will'be in electric communication with one of the lamps and keep it lighted when the gate is in operation.

Instead of a generator being used upon the engine to produce electricity the wires 2]., 24,

169, and 170 may be connected with a storage battery, with trolleyconnections leading to a local generator or with any other source of electricity.

Any style of rails or wires and any means of making rolling or sliding contact therewith may be substituted for the rails and trolleys shown. The operators switchboard need be only a few inches square and may be located at any point in the pilot-house of an engine convenient for the engineer to reachit.

By means of this invention an engineer upon his engine while it is running either forward or backward or standing still may open or close one or more gates ahead of him or behind him at will.
